Abstract: An x-ray imaging system (10), such as a X-ray computerized tomographic system, may acquire a series of radiographs at different detector positions along a first translation axis or a second translation axis parallel to orientation directions of detector pixels of a radiation detector (14). In a first embodiment, the different detector positions may be separated by a distance less than a linear size of the radiation detector (14) along the first translation axis or the second translation axis, respectively. The radiographs may be assembled into a radiograph larger than each radiograph in the series of radiographs, resulting in image stitching. In a second embodiment, the different detector positions may be separated by a distance less than a pixel size of the radiation detector (14), also referred as sub-pixel shifting of the detector. The radiographs may be assembled to form a radiograph with a higher resolution than the acquired radiographs, resulting in superresolution.

Abstract: The inventive body scanner is used to screen persons entering a security controlled area for the presence of security threats hidden under the clothing, such as guns, knifes, explosives and contraband. The Invention is an improvement on prior art body scanners that operate primarily by acquiring backscatter x-ray images, but only acquire transmission images over a limited part of the person's body. These prior art systems provide x-ray sources on the anterior and posterior sides of the person being screened, and x-ray sensitive detectors on the sides of these x-ray sources. While sufficient for backscatter imaging, the gaps between these detectors results in blind areas in the transmission images, resulting in lower ability to detect security threats hidden under the clothing. The present Invention overcomes these limitations of the prior art by providing x-ray sensitive detector on the outside of the x-ray sources.

Abstract: The present disclosure provides a method and an apparatus for generating a representation of an internal structure of an object. The method comprises the steps of providing radiation that is arranged to traverse through at least a portion of the object and directing the radiation from different angular directions through at least a portion of the object and towards an optical element, such as a lens or pin-hole. The method also comprises the step of forming a radiation exposure pattern using the optical element, the radiation exposure pattern comprising information indicative of the propagation directions and intensities of component radiation that form the radiation exposure pattern. In addition, the method comprises calculating the representation of the internal structure from the radiation exposure pattern. The method is conducted such that the radiation exposure pattern corresponds to a respective point of view of the object.

Abstract: An X-ray radiation device comprises a plurality of X-ray radiation units, each having an X-ray tube for generating an X-ray, a drive circuit for driving the X-ray tube, and a trunk line connected to the drive circuit, and a controller having a control circuit for controlling the X-ray radiation units. The trunk lines of the plurality of X-ray radiation units are connected in series to the control circuit so that the drive circuits of the plurality of X-ray radiation units are connected in parallel to the control circuit. Since the trunk lines of the plurality of X-ray radiation units are connected in series to the control circuit, the X-ray radiation units can be connected to each other and are not required to be connected one by one to the controller. This makes it possible to increase and decrease the number of units without complicating their wiring.

Abstract: Position errors of the flat-panel detector in the axes system of the radiation penetration system relative to a necessitated position which remain, for example, after a coarse setup of the radiation penetration system are balanced and thus the accuracy of the radiation penetration system is brought almost randomly close to the accuracy which would have resulted if the flat-panel detector had been exactly adjusted mechanically subsequently by executing a geometrical correction of the radiation penetration raw image, so that a change of a projection of the penetrated object in the radiation penetration raw image due to the position error is reduced or corrected.
